Question about Heating & Cooling
Hello, it's close to Summer in California and my girlfriend and I happen to live in an old apartment with poor insulation. It's gets HOT on medium temp days. We bought a USED Delonghi PAC T140 HPEC off of some one on craigslist. We since haven't been able to contact the previous owners, in regards to the recent issues. WE NEED YOUR HELP. The appliance simply wont cool down(even after clearing all existing dust from the inside.) We didn't recieve a remote so the appliance doesn't reach any lower than 64* and even at that it doesn't go chill the air like it once did. How can we fix this?

Hoses for proper connection should have been included with your purchase. Without the hoses the set-up can not be done satisfactory. One is for fresh air supply and the other is the hot air exit hose. These are normally vented out a window. Check with the dealer where you perchased the unit from. If from a private individual contact them.

I had the same problem and found a fairly simple solution. UNPLUG THE UNIT FIRST. All left and right reference below is as view from the BACK of the unit (NOT from the front). Open the right side panel (right as view from the back), by removing six screws (remove screw covers first) and pull down on the panel to remove. Towards the UPPER-back of the unit, there is a cold air evaporator(?)(bunch of tubes and fins) you can only see the edge of it after removing the right panel. Below it is a white plastic drip tray with a hole at the end allowing water to pass down to the lower warm air radiator(?) (another bunch of tubes and fins) to evaporate. If this hole is obstructed, water will over flow and leak. I cleaned out the hole with a vacuum attached to a drinking straw, you might have a better way. After cleaning, I poured a little water through to make sure it drains. There is a lower drip tray at the bottom of the unit which catches the water and you can drain it out the bottom drain hole by unplugging the rubber stopper at the back bottom of the unit. The lower drip tray has a float switch (you can only see it by removing the back panel, which you don't have to do for this procedure) which turns off the unit when the lower tray is full. So, theoretically, even if the evaporation is not working properly, as long as the upper drain hole is not obstructed, there should not be any leakage, because the water will drain into the lower drip tray and turn the unit off when it is full. The upper drain hole obstruction might be causing most of the leakage problem. Also make sure the unit is level left to right. If the left side (left as viewed from the back) is lower than the right side (as view from the back) the water in the upper drip tray might not flow to the drain hole properly and might overflow. You should also vacuum and clean the upper plastis filter screen (pull it out from the top back of the unit). Before closing the right side panel, you might want to vacuum and clean the lower warm air radiator, be careful not to damage the fins. Again before you start any of this, UNPLUG THE UNIT FIRST. This might be easier than packing and sending the over 90 pounds unit to an out of town service center. I understand some service centers might charge $100 for a simple cleaning. Consult a trained technician if you don't have the skill to do this. Do this procedure at your own risk because I am not sure if it might void you warranty. Again UNPLUG THE UNIT FIRST before you start.

It could well be low on refrigerant, as well as a multitude of other possibilities. I'd have it serviced by a pro.

Read instructions and see if it says anything about cleaning or filters. A.C units **** air in and there is a filter that probably needs cleaned.Also,while cooling, the vent to the outside should put out warm air. Also, if it is less than a year old, contact the manufacturer and they should help you out. Good luck.
